Increasing thread count might help when transferring large amount of small files but the results may vary depending on your configuration. The default parameters should work fine, but you can experiment with the values to see which ones work out the best in your environment.

Okay , Thank you Matt .

I have other question .
The default file cache was enabled in the cloudberry drive .
Is right ?
If I Increasing file cache size will be impact for what ?

Cache directory is used to store files locally before they will be uploaded to a cloud. Due to technical limitations of a virtual disk driver and the way how cloud storage providers work it's not possible to upload files on-the-fly. If you're transferring large amounts of data the software would require larger cache size, but again, you might want to tweak this option if you experience any issues during upload operations. The default values should work fine on most configurations.

Thank your reply , Matt .

So I increase cache file size of download file did not any help .

You can actually try disabling it, but since I don't know what the issue is, it's difficult to recommend something:
- Click Drive tray icon and choose Options
- Select a mapped drive and press Edit > Edit advanced options
- Uncheck "Use file cache" option
- Find the cache directory in Options > Advanced
- Navigate to that directory with Windows Explorer and delete all its contents

Thank you , Matt .

Did you known how to defined cloudberry drive tcp port ( Cloudberry drive to connect s3 object storage source port )?

We use ports 443 and 80 in our software. As for the addresses of your cloud storage provider, they should have this info on their web side.
